The concept of 4-3-1 can be good or bad, I don't think many people have tried it to prove whether it's good or not. You do risk not getting the bonuses in this set-up but you get a better pool of playable strong cards.

Some cards in the deck can be changed such as Ward Hg and Bublgmm to Cyb Lhia and C Wing, for example. But aside from the choice of cards I'd also choose the Sentinels to be the 4-card clan as their bonus (in my opinion, not based on facts) is more needed than Vortex bonus.

But at the end it's down to personal choice. If you can get a good 1400+ Elo score with that, then you'll prove that this deck does work after all.
